Method of producing marbleized flexible sheets



Patented June 3, 1 930 PATENT OFFICE GEORGE mnnvm 11106111313, or LOS ANGELES, onnrrormrn METHOD OF PRODlJ'OING MABBLEIZED FLEXIBLE SHEETS ,Ji'o Drawing.

My invention relates to a method of finishing and decorating flexible sheets preferably paper, by producing on the sur ace thereof marbleized effects so that the treated sheets 5 may be utilized for various artistic and decorative purposes, the principal object of my 1nvention being to provide a relatively simple and easily practiced method, whereby sheets of material such as paper, thin cardboard or oil cloth may be very rapidly treated so as to marbleize the surfaces thereof or produce on the surfaces an arrangement of coloring matter that veryrclosely resembles natural marble.

A further object of m invention is to provide a marbleizing met 0d of the character referred to that entirely eliminates all printing, painting or raining operations, thereby enabling the mar leized sheets to be very eco- 2 nomically produced, which latter result is of great economic advantage where a large number of the treated sheets are to be produced.

With the foregoing and other objects 1n view myjnvention consists briefly in the provision of a bath, in which sheets of paper or the like are immersed so as to absorb or pick up certain of the ingredients from said bath including coloring matter, thereby. producing on said sheets the marbleized effect. In racticing my improved method, I make use 0 a suitable container, preferably a tank that is adapted to contain water to whi'chis added alcohol, the amount of the latter being approximately one-thirtieth of the total volume of water.

The compound that is utilized with the bath composed of water and alcohol for producin the marbleized effect on the sheets is compose 40 of approximately ten pounds of white lead ground inoil and thinned with turpentine of suflicient quantity of producin a gallon of the mixture. To this gallon 0% mixture is added ap roximately one-sixtieth in volume of raw or oiled linseed oil about one-thirtieth by volume of benzol, about one-fifteenth b volume of acetic acid about one-hundredt part by volume of a suitable drier, referably japan, approximately one-fortieth by volume of hypo-sulphite and sufiicient pigment or colors and the sheets are now ready for use.

oring matter to produce the. desired color and effect.

The various ingredients just mentioned are thoroughly mixed with the base of white lead and turpentine, and when sheets of paper or the like are to be treated a small quantity of the base mixture is, with a brush or the like, thrown with a quick or whipping motion onto the surface of the bath, and immediately thereafter a sheetof paper is positioned flatwise upon the surface of the bath and immersed slightly below the surface thereof, and then drawn upwardly with a sweeping motion out of the bath and said sheet is the laid aside to dry.

The sheet is immersed in the bath for only a very short period of time, but on contact with the surface of said bath, the sheet absorbs and picks up the base compound including the pigment or coloring matter, and within a few seconds after it has been withdrawn from the bath it is dry and ready for further treatment or-use.

In some instances, hydro-chloric acid may be used instead of acetic acid, but in either case the acid causes the com ound' that is thrown onto the surface of the ath to spread over the surface of the bath so as to be engaged by the paper when immersed therein, the hypo-sulphite acts on the paper so that the same readily receives the compound in cluding the coloring matter and the benzol penetrates the paper and causes the coloring matter to adhere thereto. The drier or japan sets the oil that carries the color and assists $5 materially in the drying action.

The alcohol that is combined with the water that forms the bath on which the coloring material is floated, is utilized fgr the purpose of neutralizing the oil used in grinding the white lead and thus the oil is'prevented from forming globules on the surface of the bath when the paper is immersed therein and which globules, if permitted, form undesirable spots on the treated paper.

Immediately after the sheets have been immersed in the bath and withdrawn there-'' from the action of the air oxidizes the colored surface thereof, thereby setting the col- The sheets ma be applied to frames or forms through t e use of ordinary .papersheets are immersed in the bath.
